6m4cahs the issues with no image is usually related to :"

"- Ensure the Signal Cable and Source work (If you connect multiple sources at the same time, use the "Source" button switch)- Ensure all connectors are securely connected and aren’t broken- Check Main Board- Check Engine Module- Check DMD Board- Check DMD Chip"

Seems to start to get a bit complicated. Let us know if you are up to taking it apart and checking a few things. You'll need some hand tools as well as a multimeter. You want to take as many pictures as possible and post those with your question. For that use this guide
